SPECIFICATION forming part of Letters Patent No. 604,554, dated May 24, 1898.

Application tiled November 18, 1895. Serial No. 569,290. (No model.)

To @ZZ whom t may concern:

Beit known that I, ROBERT WISE, a citizen of the United States, residing at the city of New York, in the county and State of New Yorlghave invented an Improvement in Hose- Nozzles, of which the following is a specification.

The object of this invention is to allow for throwing a straight stream and for projecting an annular spray to drive back smoke and heat in case of fire, the improvement being available either as a nozzle for fire-hose or as a sprinkler for agricultural or horticultural purposes.

vThe special feature of the present invention relates to the means for turning on or shutting off the annular spray during the time that the straight stream may be in use, so as not to have to stop or shut off the straight stream in turning on or off the spray or in adj usting the spread or force of such spray.

In the drawings, Figure 1 is a longitudinal section of the improved hose-nozzle, and Fig. 2 is an end view of the same. a

The nozzle is made with a body A in one piece, comprising the screw-thread or coupling 3, by which the nozzle is connected with or disconnected from the hose, and the barrel 4. of the body receives the plug B of the cock, and this is provided with a handle 5, by which it may be turned. This cock is of ordinary construction and through it is a straight waterway 6, coinciding with the bore 7 of the body of the nozzle, and the screw-thread portion 8 is at the forward end of the nozzle-body.

The jet-nozzle C may be formed in one piece with the body A or otherwise connected to the same, there being arms 9 between the jetnozzle C and the body A near the screw-thread 8, and it is advantageous to make the opening or bore of the j et-nozzle C slightly smaller than the bore '7 of the bodyA, and at the outer end of the jet-nozzle is an enlargement with a screw-thread 10, adapted to receive a blind cap D when the straight stream is not to be used or to receive a reducer E for throwing a smaller stream when desired. This blind cap and reducer are well known in nozzles heretofore constructed, and in order to prevent such blind cap or reducer being lost projections 11 and 12 in the form of internallythreaded rings are provided at opposite sides of the nozzle, preferably upon the sides of the barrel Ll.

The special feature of the present invention applies to the conical flange F, which is a iiX- ture around the jet-nozzle C, and the adjustable bell G, having a screw-thread at l3,screw ing upon the screw-thread 8, so as to be adj ustable longitudinally of the nozzle, and between the edge 14 of the bell and the edge 15 of the conical flange F the water can be allowed to issue to a greater or less extent as the bell G may be adjusted to open or close such space, and it is advantageous to make use of a lock-nut H and flexible washer 16 to prevent leakage between screw-threads 13 and 8 and also to hold the parts reliably iu the position to which they may be adjusted.

It will now be understood that the water can be entirely shut off between 14c and 15 by simply adjusting the bell G, so that the water can be allowed to issue with any desired force by adjusting such bell regardless of the stream which may be issuing from the jetnozzle C, and in this manner a fireman is able to direct the jet from the nozzle C upon the fire, or should the smoke or flame suddenly be blown toward him he can instantly drive the same back by opening the annular spray with such a force as to not only protect himself from'such flame but drive back. the heat and smoke.

Should it become necessary in the final extinguishment'of ires to make use of the annular spray for wetting walls and extinguishing small lires without the use of the powerful jet from the nozzle C, the water can be stopped by turning the plug B and the blind cap D screwed upon the end of the jetnozzle and the spray only usedfrom the annular space between the edges 14 and 15 when the plug B is turned.

A band of rubber around the nozzle is advantageously employed, as shown at Il', to lessen the risk of injury to the edges of the bell by concussion, and ribs at L upon the exterior of such bell facilitate the handling of the bell in rotating the saine to vary the spray that is thrown from the nozzle.

In consequence of the peculiar shape of the edges 14 and l5 the spray or annular stream may be contracted and directed forward when the edges are near each other, or the annular IOO stream may be spread and broadened when the bell is screwed back to increase the Volume of such stream, the curvature of the inner surface of the iange F throwing the water outward.

I claim as my inventionl. The hose-pipe nozzle having a body with a shut-off cock and a coupling portion at its rear end screw-threaded at :its forward end, a jet-nozzle extending forward of the body and having a flan ge around it, the body, shutoff cock, coupling portion, jet nozzle and flange being permanently and rigidly connected, in combination with a bell screwthreaded at its rear end to tit the screw-thread upon the body and adapted to vary the annular opening between its front end and the fiange by screwing it forward or backward, substantially as set forth.

2. The hose-pipe nozzle having a body with a shut-olf cock and a coupling portion at its rear end screw-threaded at its forward end, a jet-nozzle extending forward of the body and having a flange around it, the body, shutoff cock, coupling portion, jet nozzle and flange being permanently and rigidly conneeted, in combination with a bell screwthreaded at its rear end to fit the screw-thread upon the body and adapted to vary the annular opening between its front end and the flange by screwing it forward or backward, a look-nut and washer adjacent tothe rear end of the adjustable bell, substantially as set forth.
